Transcript of "Fluke Scopemeter - 190 Series II"

  1. 1. What could you do with four Feedback channels? Analog/Digital Take multiple measurements simultaneously and track down the Safety control root cause of your most complex Output troubleshooting challenges. Analog Condition Input Process/Display Digital Power Supply Easily diagnose timing-related issues with multiple signals Transducers • Real-time inspection of multiple related Measurements’ signals simultaneously • Measure a combination of input and output For industrial electronics, four channels allows you to signals and system safety interlocks and perform three-dimensional testing, measuring input, feedback loops output and feedback signals simultaneously. Find problems in industrial systems including: • Circuit voltage/current overloading • Attenuation/input impedance mismatch • Signal fluctuation/drift Mains AC to DC DC lter DC to AC converter • Conditioning circuits signal integrity supply conversion and buffer • Test point verification for critical signals +Vdc • Input/output/feedback timing issues • Induced noise and disturbances • Random shutdowns/reset L1 bus voltage T1 T2 Diagnose VSDs or power inverters and L2 T3 converters L3 • Harmonics, transients and loads in three- phase power input Gnd • Troubleshoot dc to ac converters for faulty -Vdc control circuits or output IGBT gate stages • Cable interface—test PWM output for reflec- Mechanical output Motor (load) Cable interface tions and transients T3 T2 T1 In three-phase systems like variable speed drives, UPS or back-up generators, use four channels to diagnose power input, dc to ac converters, or cable interface problems.5
